当 WooCommerce 中的自定义订单状态发生变化时发送电子邮件通知

问题描述：

我在 WooCommerce 中创建了一个名为 Back Order (wc-backorder) 的自定义订单状态:

I have created a custom order status in my WooCommerce called Back Order (wc-backorder):

/**
     * Add custom status to order list
*/
    add_action( 'init', 'register_custom_post_status', 10 );
    function register_custom_post_status() {
        register_post_status( 'wc-backorder', array(
            'label'                     => _x( 'Back Order', 'Order status', 'woocommerce' ),
            'public'                    => true,
            'exclude_from_search'       => false,
            'show_in_admin_all_list'    => true,
            'show_in_admin_status_list' => true,
            'label_count'               => _n_noop( 'Back Order <span class="count">(%s)</span>', 'Back Order <span class="count">(%s)</span>', 'woocommerce' )
        ) );

}

/**
 * Add custom status to order page drop down
 */
add_filter( 'wc_order_statuses', 'custom_wc_order_statuses' );
function custom_wc_order_statuses( $order_statuses ) {
    $order_statuses['wc-backorder'] = _x( 'Back Order', 'Order status', 'woocommerce' );
    return $order_statuses;
}

现在我想在收到已提供状态报价的订单时收到一封电子邮件.我根据这篇有用的文章创建了一个插件:如何添加自定义 WooCommerce 电子邮件

Now I want to receive an email whenever an order is received that has been given the status quote. I've created a plugin based on this helpful article: How to Add a Custom WooCommerce Email

此链接包含我的插件源代码和functions.php代码.

This link is containing my plugin source code and the functions.php code.

我在 function.php 中添加了钩子:

I added hook in function.php:

add_action( 'woocommerce_order_status_wc-order-confirmed', array( WC(), 'send_transactional_email' ), 10, 10 );

function so_27112461_woocommerce_email_actions( $actions ){
    $actions[] = 'woocommerce_order_status_wc-order-confirmed';
    return $actions;
}
add_filter( 'woocommerce_email_actions', 'so_27112461_woocommerce_email_actions' );

当订单更改为延期交货"状态时，没有任何反应.

Nothing happens when an order changed into the 'Back Order' status.

有什么想法吗?

我尝试了大量不同的钩子，但似乎无法运行触发函数.

I've tried loads of different hooks but I can't seem to get the trigger function to run.

我使用的是最新版本的 WordPress 和 WooCommerce (3.0+)

I am on latest versions of WordPress and WooCommerce (3.0+)

谢谢

- EDIT/UPDATE -

由于您使用的代码教程对于这个新的大型主要版本 3.0+ 来说真的已经过时了(2013 年)，这个挂在 woocommerce_order_status_changed 动作钩子中的自定义函数将执行工作.因此，当订单状态更改为您的自定义状态时，您将能够发送自定义处理电子邮件通知.

As the code tutorial you are using is really outdated (2013) for this new mega major version 3.0+, this custom function hooked in woocommerce_order_status_changed action hook will do the job. So You will be able to send a customized Processing email notification, when order status is changed to your custom status.

这是 WC 3.0+ 的工作和测试代码:

Here is that working and tested code for WC 3.0+:

add_action('woocommerce_order_status_changed', 'backorder_status_custom_notification', 10, 4);
function backorder_status_custom_notification( $order_id, $from_status, $to_status, $order ) {

   if( $order->has_status( 'backorder' )) {

        // Getting all WC_emails objects
        $email_notifications = WC()->mailer()->get_emails();

        // Customizing Heading and subject In the WC_email processing Order object
        $email_notifications['WC_Email_Customer_Processing_Order']->heading = __('Your processing Back order','woocommerce');
        $email_notifications['WC_Email_Customer_Processing_Order']->subject = 'Your {site_title} processing Back order receipt from {order_date}';

        // Sending the customized email
        $email_notifications['WC_Email_Customer_Processing_Order']->trigger( $order_id );
    }

}

此代码位于活动子主题(或主题)的 function.php 文件或任何插件文件中.

因为你的自定义状态是wc-backorder，而不是wc-order-confirmed，你只需要到处替换wc-order-confirmed by wc-backorder.

AS your custom status is wc-backorder, but not wc-order-confirmed, you just need to replace everywhere wc-order-confirmed by wc-backorder.

要使其工作，您必须以这种方式更改最后两个挂钩的函数:

To make it work, you will have to change the 2 last hooked functions this way:

add_action( 'woocommerce_order_status_wc-backorder', array( WC(), 'send_transactional_email' ), 10, 1 );


add_filter( 'woocommerce_email_actions', 'filter_woocommerce_email_actions' );
function filter_woocommerce_email_actions( $actions ){
    $actions[] = 'woocommerce_order_status_wc-backorder';
    return $actions;
}

代码位于活动子主题(或主题)的 function.php 文件或任何插件文件中.

这应该有效(我无法测试它，因为没有自定义插件的代码).

This should work (I can't test it as there is no the code of your custom plugin).
